<p>This example shows how to style an element using Node.</p>
</div>
<div class="example">
<style>
.example #demo {
background-color: #D4D8EB;
border: 1px solid #9EA8C6;
border-radius: 3px 3px 3px 3px;
box-shadow: 3px 3px 5px rgba(0, 0, 0, 0.25);
width: 20em;
margin-bottom: 1em;
}
.example #demo em{
font-size: 150%;
font-style: normal;
margin-right: 0.3em;
}
.example dt {
font-weight: normal;
}
.example dd {
font-size: 150%;
line-height: 0.5em;
}
</style>
<div id="demo">
<p><em>Click me</em> to change my text color and show some style information.</p>
</div>
<dl>
<dt>style.color</dt>
<dd>black</dd>
<dt>computedStyle.color</dt>
<dd>rgb(0, 0, 0)</dd>
</dl>
<script type="text/javascript">
YUI().use('node', function(Y) {
var onClick = function(e) {
var node = e.currentTarget;
node.setStyle('color', 'red');
var styleColor = node.getStyle('color'),
computedColor = node.getComputedStyle('color');
Y.one('.example dl').setContent('<dt>style.color</dt><dd>' +
styleColor + '</dd>' +
'<dt>computedStyle.color</dt><dd>' +
computedColor + '</dd>');
};
Y.one('#demo').on('click', onClick);
});
</script>
</div>
<h2>Setting up the HTML</h2>
<p>First we need some HTML to work with.</p>
<pre class="code prettyprint"><div id="demo">
<p>Click me to change my color and show some style information.</p>
</div></pre>
<h2>Using Style Methods</h2>
<p>In this example, we will set the node's color and compare the style and computedStyle values when our demo node is clicked.</p>
<pre class="code prettyprint">var onClick = function(e) {
var node = e.currentTarget;
node.setStyle('color', 'red');
var styleColor = node.getStyle('color'),
computedColor = node.getComputedStyle('color');
Y.one('.example dl').setContent('<dt>style.color</dt><dd>' +
styleColor + '</dd>' +
'<dt>computedStyle.color</dt><dd>' +
computedColor + '</dd>');
};</pre>
<p>The last step is to assign the click handler.</p>
<pre class="code prettyprint">Y.one('#demo').on('click', onClick);</pre>
